And check out the average Victorian result: 4 worlds!This is a scary number.

My bitch and moan: this calculator is an oversimplification of our impact on the world eg the issue of the impact of meat versus processed foods. The calculator asks whether animal products are eaten, which of course contribute to greenhouse gas through methane production, but nothing is made of the impact of highly processed food through its creation and distribution.

Having said that, though, this is a great calculator for getting a handle on your impact on the world, and I recommend everybody does it.
